Case Type   : mot不支持的索引
Case Name   : MOT表不支持在总列宽>256的表上创建索引，数据类型为float4
Create At   : 2020/09/18
Owner       : opentestcase028
Description :
    1.设置enable_incremental_checkpoint参数为off,并重启数据库
    2.MOT表不支持在总列宽>256的表上创建索引，数据类型为float4
      键大小包括以字节为单位的列大小+列附加大小，其是维护索引所需的开销(详见表格不同类型对应的列附加大小)
      如果索引不是唯一的，需要额外的8字节
    3.恢复环境默认配置，修改enable_incremental_checkpoint为on，并重启数据库
Expect      :
    1.设置成功，重启数据库成功
    2.普通索引创建失败，唯一索引创建失败
    3.修改参数成功，重启数据库成功
